Security Alert


At Texas National Bank, we believe that one of our most important jobs is to provide security for our customers. MasterCard recently notified us of an incident in which certain card information could have been compromised through a third party, including those of some of our customers.

We are currently notifying the affected cardholders via phone, will be monitoring accounts and reissuing cards as soon as possible. We ask that you please monitor your account and notify us immediately if you see any unauthorized activity. We appreciate your patience since this is a nationwide incident and there might be some delays. If you have any questions or concerns, please contact us 956-217-7100.
